Christians who approve of assisted dying don't line up with the will of God because the will of God is found in his word and the word of God says in Isaiah 53:5 and in Matthew 8:16 to 17 that by his stripes we were already healed by the cross in the same way that there was no sickness or disease back in the garden before the fall. Anybody who calls themselves a Christian and who agrees with assisted suicide is conforming to this world, this world of the first Adam, a world that is sick and dying spiritually, emotionally and physically, but as believers we have the good news and part of that good news is healing belongs to those who believe as we see Jesus going around doing good healing all manners of sickness and disease and then raising up his first disciples to do the same thing, and this belongs to the church the body of Christ. The Head has not changed therefore the Body has to line up with the Head.
